. 2 Claims- I (or. ez-co' This invention pertains to liquid cooling appe= retus. More particularly, it pertains to n device for holding in place in a refrigerator a standard container, as, :for example, a bottle. In a prelei-red species of the invention, a standard hall gallon or one gallon bottle is employed.

It has-heretofore been proposed to ems: motel cooling tanks to reirigerators, such tanks, so tar as I am aware, being permanently mounted. It has been proposed to have said tanks discharge through a valve or faucet on a pipe projecting through the refrigerator to the outside, so that, to clean the tank, it is necessary to unscrew the valve and dismantle the device. It is practically impossible to clean such tanks while mounted in place on a refrigerator door. For the most part such tanks, made or metal, do not provide easy observation of the amount of liquid and other conditions obtaining within the tank. The filling of such tanks can be accomplished only by pouring the liquid lnthrough an opening at the top.

it is an object of this invention, among other objects, to overcome these many dificulties.

To that end, I have provided means for mounting on the interior of a refrigerator, as on the door, a standard container, of which a galion or hair gallon bottle is an example. In many sections of the country, it is customary -9 to purchase distilled or spring water in bottles insuch half gallon and one gallon sizes. Such a bottle, mounted on the interior of a refrigerator, does not require a great deal of space and has a great many advantages for the purposes ,5 which I have in mind. For example, it is a simple matter, in the invention which I have made, to substitute one or these standard containers ror another. It is correspondingly easy to keep the containers clean and in a sanitary my condition. The refilling is not accomplished at the refrigerator, but elsewhere; so that it is merely necessary to insert a bottle of water in the device and allow the water to cool. Other features of novelty of the invention re- 5 side in the fact that when the device herein described is employed in a refrigerator it does not detract from the effective insulation of the wall or door. In the prior art, the tanksheretofore known have been set in the walls or/in the door of the refrigerator, thereby decreasing substantially the effective insulation. In the present case, the bottle in question stands somewhat away from the wall, which can be of a normal thickness, so that there is no loss in efiiciency due to increased heat transfer. At the same time, the transparency of the glass of which the bottle is made permits the quantity of liquid within the bottle to be easily ascertained,

Briefly stated, my invention comprises a receptacle into which the mouth of the inverted co container extends. Connected with such receptacle by a suitably mounted pipe is a valve or faucet, the some being preferably mounted on the exterior of the refrigerator. it is not necessary, however, that the said valve be 5- mounted exteriorly, as it muy conveniently be mounted on the inside in conjunction with the cooling apparatus. Ordinarily, it will be preferred to mount the faucet on the outside for the reason that there is no loss in emciency in 7 withdrawing. liquid in-such manner; whereas if the door has to be opened to permit withdrawal of liquid there is o. considerable inflow of warm air into the refrigerator as e whole. Conveniently, the apparatus may he mounted on the 7 door of a refrigerator, but it may also be mounted within it in any suitable position. Thus, for example, it may be mounted on or near a dividing partition between two doors of the refrigerator. In such case, the valve may go be mounted on the outside of the partition.

In the accompanying drawings, forming a part hereof, which represent illustrative embodiments of the invention,

Figure 1 shows, in front elevation, s. two-door refrigerator in which is mounted the apparatus of the present invention;

Figure 2 shows a single-door refrigerator in which the unit herein described is mounted on the inside of the door, the faucet being shown as on the inside;

Figure 3 is an enlarged view of the unit employed in Figure 2;

Figure 4 is an elevation of a single-door refrigerator equipped with the invention, the faucet being on the exterior;

Figure 5 is a side elevatio with parts in section, of the apparatus of Figure 4, showing a half gallon bottle properly mounted:

Figure 6 is a side elevation, with parts in 10 section, showing a one gallon mounted in the same manner;

Figure 7 is a perspective of the standard, showing the receptacle into which the container extends and thespring retaining means for holding the bottle securely in place; 1

Figure 8 is a detail view showing said spring retaining means.

Referring to'Figure 1 of the drawings, the character 1 designates the refrigerator as a no whole, the said refrigerator having the door 2 for the compartment in which the cooling unit 21 of the refrigerator is mounted, the door 3 for the principal food compartment, and the partition 4 separating said doors. By means of the apparatus herein described, the bottle 5 is held in place in such manner that liquid may be withdrawn from the outside. In the drawings, the apparatus is shown as mounted on the face of the cooling unit of the refrigerator.

Figure 2 shows a single door refrigerator in which the refrigerator itself is designated 1, the door is designated 2, and the bottle is designated 5, as before. In Figure 1, the character 6 desighates the shelving within the refrigerator, as also in Figure 2. In the latter, however, part of the uppermost shelf is cut away at 7 to accommodate he receptacle which forms a part of the present invention. The bottle is mounted on the inside of the door 2. Water may be withdrawn by of valve 12, mounted on the inside of the door.

Figure 3, a detail view corresponding to Figure 2, shows the bottle 5 mounted on the interior of the door 2 in accordance with the teachings of the present invention. Features here shown are the receptacle 8 into which the bottle 5 extends, the retaining spring 9, shown toward the top of the bottle, and the standard 10, shown in dotted lines back of the bottle 5. The valve is designated 12.

Figure i shows a single-door refrigerator in which is mounted the cooling apparatus of the present invention. It differs from that of Figure 2 in that the valve in Figure 4 is on the outside, rather than of the inside of, the door.

Figures 5 and 5 show side elevations, respectively, of a half gallon and a one gallon bottle properly mounted in accordance with' this invention. In both, the shelf 6 is cut away at 7 to accommodate the receptacle 8. The latter is provided with a suitable aperture into which is threaded the pipe 11, the same extending through the door 2 of the refrigerator to the exterior. On the outside end of the pipe 11 is mounted the faucet 12, preferably of the push button type, as shown in the drawings. The receptacle 8 is provided at its uppermost portion with an annular gasket 13, which may be made of leather, rubber, or equivalent material. The r ceptacle 8 is beaded over, as at 14, to make an annular socket to hold the gasket in place.

The gasket 13, compressed by weight of the bottle and contents, makes a tight joint between the bottle 5 and the receptacle 8. Whether the bottle 5 be of the one gallon size depicted in Figure 5 or of the half gallon size depicted in Figure 5 makes little difference, for it is the rounded shoulder of the bottle which rests on the gasket. The receptacle 8, with attached pipe 11 and gasket 13, is mounted on the bracketlike standard 10, which is formed, preferably stamped from heavy sheet metal, with a vertically extending body 15, a horizontally extending bottom flange 16, and lateral buttress strips 17. The receptacle 8 rests on and may be welded or otherwise suitably fastened to the bottom flange 16 and to the side buttress strips.

Toward the top of the standard 10 are the lateral lugs 18, constituting part of the means for supporting the bottle 5. Above the'lugs 18 are lugs 19, adapted to cooperate with a larger bottle than that adapted for use with lugs 18. As shown in Figures 5 and 6, the lower set of lugs, designated 18, is used in conjunction with a half'gallon bottle, while the upper pair of lugs is employed with the larger one gallon bottle. In either case, an elastic ligature or band which is illustrated as being a coil spring 9, is by means of open links 20 hooked over lugs 18 or 19, as the case may be, and looped around the bottle 5 to hold it in place.

In operation, the coil spring 9 is aflixed, by the links 20 to lugs 18 or 19, as desired. The bottle 5 is then brought into juxtaposition with the apparatus, whereupon the bottle 5 is inverted, and its mouth placed within the receptacle 8. 'Hie bottle 5 is then lowered until its rounded shoulder rests on the gasket 13. Thereafter, the coil spring 9 is'stretched from the loose position shown in Figure 7 to enable it to accommodate the bottle. It is slipped as a loop around the uppermost portion of the inverted bottle and is then brought into the position shown in Figures 5 and e. In this position, it cooperates with the lugs 18 or 19, as the case may be, to hold the bottle 5 firmly in position vertically over the gasket and receptacle 8.

When the faucet 12 is operated, the liquidwithin the container 5 is discharged therethrough. If the faucet be mounted on the outside of the refrigerator, this withdrawal of liquid is accomplished without loss of efficiency. In any event, the iiquid withdrawn is replaced by air until the container is entirely emptied of liquid.

Thus by simple and inexpensive means I have provided for the mounting of a standard gallon or half gallon bottle 01 water on the interior of a refrigerator, either on the. refrigerator itself or on the door thereof. be affixed there by bolts or by welding or otherwise, the welding being perhaps preferable, and may receive the same finish as the interior of the refrigerator. The receptacle 8 being finished in the same manner, the apparatus as a whole presents a neat and clean appearance. The coil spring 9 can conveniently be made from some non-tarnishing metal, as a chromium alloy, or be chromium-plated to prevent rusting.

It is not entirely necessary that the receptacle 8 be rigidly mounted, although this is a convenient way of handling the matter. It may, for instance, be pivoted, for example on a horizontal axis, in which case it might be supported on the pipe 11, the flange 15 being omitted, and thus be adapted to receive the bottle 5 in any of several positions. Then if the receptacle 8, mounted thus, or otherwise mounted and provided with a flexible connection to the pipe 11, be swung into a position in which the mouth of the receptacle is downward, the bottle 5 may be brought into juxta-position with the receptacle .while the bottle is still upright and in its normal position. The receptacle 8 and the bottle 5 may then be swung into the position it employs in the present invention, whereupon the coil spring loop 9 may be forced over the uppermost portion of the bottle to hold it in place. If preferred, other means than the coil spring may be employed, as, for example, a strip of sheet metal serving as a band around the bottle or toggle means extending from the top of the bottle to the bottom. On the whole, the apparatus shown in the accompanying drawings is a simple and desirable form of the invention.

From the foregoing, it will be apparent that numerous advantages result from the use of this invention in the cooling of liquids in refrigera- The standard may therefore desire that tors. For example, the invention provides sanitary conditions within the container in that the glass bottles or other interchangeable containers herein employed are customarily ilized and rinsed before being filled. As hereinbefore stated, standard containers of half gallon or one gallon sizes are employed in large quantities throughout the country, being filled for the most part with spring water or with distilled water. The present invention makes possible the use or these containers in the form in which purchased; 1. e., without necessitating the transfer of. the contained distilled or spring water to some other container.

Other advantages reside in the fact that the glass used in the half gallon or one gallon bottles permits easy view of the conditions obtaining within the bottle. Likewise, it can be ascertained at a glance whether or not the bottle is in need of filling or replacement, which is something notheretofore possible. Ihe increased ease of filling, as compared with prior art liquid cooling apparatus, is considerable. Added to this is the fact that the device as a whole does not decrease the insulation of the refrigerator. Also, in the invention herein described the body of liquid is not, as heretofore, exposed to the air within the refrigerator to increase the humidity to an undesirable extent and to make necessary more frequent de-frosting; instead, the liquid is kept within a container in which evaporation to the interior of the refrigerator is prevented.

Obviously, modifications may be made from time to time by those skilled in the art and I only such limitations as are imposed by the prior art be placed on the accompanying claims. It is intended that the patent shall cover. by suitable expression in the claims, whatever features of patentable novelty are disclosed herein.
